'Sword' in the Bible

Think not that I am come to send peace on earth: I came not to send peace, but a sword.

And, behold, one of them which were with Jesus stretched out his hand, and drew his sword, and struck a servant of the high priest's, and smote off his ear.

Then said Jesus unto him, Put up again thy sword into his place: for all they that take the sword shall perish with the sword.
